These models, however, assume the number of retransmissions is constant or unlimited, which lead to higher delay and lower throughput.
In addition, average delay and loss rate in the network depend on the total network load,, for example, high load in the network lead to higher delays and losses.
At the same time, the proposed method leads to higher delay as compared to greedy forwarding, owing to higher number of hops to the destination in the former case.
In addition, the hierarchical domain is not considered also in their work, which may lead to high queuing delay.
However, the centralized datacenter structure may lead to high service delay, especially for real time and high bandwidth streaming services.
It can be seen that when the traffic density is high, the CMGM will lead to high data transmission delay.
Congestion will lead to high packet loss, long delay, and a waste of resource utilization time.
In such applications, retransmitting failed packets without applying forward error correction techniques can lead to high energy losses and delay.
While adequate PCEC access is particularly important in rural areas isolated from urban centers, inadequate utilization of such centers may lead to higher costs, delayed or ineffective response to emergencies, and loss of continuity of care by general practitioners [ 12].
They also report that job strain associated with airline delays and tight schedules tends to lead to high blood pressure.
